Definitions
- the present invention relates to medicaments for enhancing the effect of cancer therapy on the basis of mechanism of injuring DNA, and novel compounds useful as active ingredients of said medicament.
- Anticancer agents are administered in treatments of cancer patients at present. However, their life-prolongation rates are undesirably low, and moreover, cancer patients administered with an anticancer agent are forced to tolerate severe side effects such as fever, nausea, epilation, chill, fatigue, immune malfunction, gastrointestinal disorder, liver disorder, and kidney disorder, which becomes a cause of significant deterioration of the QOL (Quality of Life) of the cancer patients. Furthermore, reduction of sensitivity of cancer cells to anticancer agents, caused by the use of the anticancer agents, may lead to prolonged administration period of administration of the anticancer agents and increase of doses, and as a result, deaths resulting from side effects of the anticancer agents are often observed.
- QOL Quality of Life
- anticancer agents may spoil advantages of patients, as well as significantly diminish social and economic benefits. This is caused by the fact that anticancer agents, which are expectedly used to exhibit selective cytotoxicity to cancer cells that disorderly divide and proliferate, actually act cytotoxically on normal cells, particularly on cells in the intestine and marrow.
- the action is presumed to be based on a destruction of a certain part of the cell cycle (for example, G1 period and G2 period: Cancer Res., 60, 2108-2112, 2000 ; Cancer Res., 59, 4375-4382(1999) , since caffeine and UCN-01 inhibit protein kinases involved in a control of a cell cycle ( J. Biol. Chem., 275, 10342-10348, 2000 ; Cancer Res., 61, 1065-1072, 2001 ). However, no conclusive evidence has been obtained.

Abstract
Description
- The present invention relates to medicaments for enhancing the effect of cancer therapy on the basis of mechanism of injuring DNA, and novel compounds useful as active ingredients of said medicament.
- Anticancer agents are administered in treatments of cancer patients at present. However, their life-prolongation rates are undesirably low, and moreover, cancer patients administered with an anticancer agent are forced to tolerate severe side effects such as fever, nausea, epilation, chill, fatigue, immune malfunction, gastrointestinal disorder, liver disorder, and kidney disorder, which becomes a cause of significant deterioration of the QOL (Quality of Life) of the cancer patients. Furthermore, reduction of sensitivity of cancer cells to anticancer agents, caused by the use of the anticancer agents, may lead to prolonged administration period of administration of the anticancer agents and increase of doses, and as a result, deaths resulting from side effects of the anticancer agents are often observed. Therefore, the administration of anticancer agents may spoil advantages of patients, as well as significantly diminish social and economic benefits. This is caused by the fact that anticancer agents, which are expectedly used to exhibit selective cytotoxicity to cancer cells that disorderly divide and proliferate, actually act cytotoxically on normal cells, particularly on cells in the intestine and marrow.
- In recent years, reports have been made on caffeine which is a low molecule organic compound and UCN-01(7-hydroxy staurosporine) having actions to enhance radiation susceptibility of cancer cells which are radiation resistant (J. Biol. Chem., 275, 5600-5605, 2000; J. Biol. Chem., 276, 17693-17698, 2001). Cancer therapy by radiation is also based on the mode of action of artificial injury of DNAs, and is considered to be basically equivalent to anticancer agents such as bleomycin based on the mode of action of DNA injury. Accordingly, it is believed that a drug that enhances selective toxicity to cancer cells can be developed even for anticancer agents based on the mode of action of DNA injury which are available at present.
- In fact, it is reported that caffeine increases the actions of anticancer agents such as adriamycin, cisplatin, cyclophosphamide, and mitomycin C based on the mode of action of DNA injury (Jpn. J. Cancer. Res., 80, 83-88, 1989). However, potency remains insufficient, and separation from toxicity is unsatisfactory. UCN-01 is also reported to enhance actions of several kinds of anticancer agents based on the mode of action of DNA injury (Invest. New Drugs, 18, 95-107, 2000).
- As for the mode of action of the potentiation of anticancer agents, the action is presumed to be based on a destruction of a certain part of the cell cycle (for example, G1 period and G2 period: Cancer Res., 60, 2108-2112, 2000; Cancer Res., 59, 4375-4382(1999), since caffeine and UCN-01 inhibit protein kinases involved in a control of a cell cycle (J. Biol. Chem., 275, 10342-10348, 2000; Cancer Res., 61, 1065-1072, 2001). However, no conclusive evidence has been obtained. In addition, since caffeine and UNC-01 as a staurosporin derivative have inhibitory actions against multiple kinds of protein kinases (Biochem. Biophys. Res. Commun., 219, 778-783, 1996; Acta Pharmacol. Sin., 21, 35-40, 2000), a possibility of involvement of a mechanism other than the destruction of the cell cycle can not be denied. Accordingly, a clear mode of action remains unidentified. Furthermore, there is a high possibility that these agents have inhibitory actions also against protein kinases participating in intracellular signal transduction, which is considered to be a possible cause of inducing serious side effects.

EP 0 558 258 discloses sulfonamide endothelin antagonists for treating diseases like hypertension. MEDLINE abstract NLM3677086, Int.J.Biochem. 19(11) 1091-1095, 1987, MEDLINE abstract NLM6541042 and EMBASE abstract EMB-1998407723 disclose the enhancement of antineoplastic effects by using calmodulin antagonists (e.g. W-5, W-7 and W-13). - As explained above, no effective means is available at present to solve various problems caused by the cancer therapies based on the mode of action of DNA injury. Developments of new drugs or therapies, that potentiate the effects of available anticancer agents and radiation therapy based on the mode of action of DNA injury and that enhance selectivity to cancer cells to decrease side effects, will contribute to increase the QOL and advantages of cancer patients as well as social and economic benefits.
- An object of the present invention is to provide medicaments for enhancing the effect of cancer therapy based on the mode of action of DNA injury. More specifically, an object of the present invention is to provide medicaments which, per se, have weak anticancer activity (cytotoxicity), but in combination of an anticancer agent based on the mode of action of DNA injury or a therapy such as radiation which gives artificial injuries to DNA, can selectively damage or kill cancer cells at a lower dose of anticancer agent or a lower radiation dose so as to significantly reduce affects on normal cells. Furthermore, another object of the present invention is to provide medicaments to reduce side effects resulting from cancer therapy by potentiation of the effects of the above cancer therapy and by reduction of a dose of the anticancer agent and/or radiation dose. Still further object of the present invention is to provide novel compounds which are useful as active ingredients of the above medicaments.
- The inventors of the present invention focused on protein kinase inhibitors to solve the aforementioned objects, and carried out search for compounds having desired pharmacological activities by using computerized molecular design technology as a means to discover candidate compounds.

The inventors classified the resulting compounds on the basis of their skeletons, and by using several typical compounds, they carried out tests of combined effects with bleomycin on cancer cells and normal cells and tests of cytotoxicity to cancer cells and normal cells when the compounds are used alone. The inventors selected compounds having strong and desired pharmacological activities, and further prepared their derivatives to achieve the present invention.

Materials and methods are as follows. Jurkat cells obtained from Dainippon Pharmaceutical Co. Ltd. were inoculated at about 10,000 cells per well in a 96 well culture plate, and incubated in 10% bovine fetal serum (Irvine Scientific) supplemented with RPMI1640(ICN) medium in 5% CO2 incubator at 37°C. For the culture, each compound was added alone, or the culture was further added with bleomycin (Wako) to give a concentration of 5 µ g/ml or 10 µ g/ml. 36 hours after the incubation, the number of living cells was counted by the MTS method.
- More specifically, 20 µl of CellTiter96™ AQueous One Solution (Promega) was added per one well, and after the cells were incubated for additional one hour, an absorbance at 490nm was measured by using a microplate reader. The same culture added with DMSO as a solvent at final concentration of 0.25% was used as a control. The number of cells in the control was considered as 100% survival rate, and for each compound, survival rates by sole administration or a combined administration were calculated. Treatments solely with bleomycin at 5µg/ml or 10µg/ml gave about 5 to 10% of decrease in the survival rates of the Jurkat cells. Whilst, when the compound of the present invention coexisted, the survival rates of the Jurkat cells by bleomycin at 5µg/ml or 10µg/ml were remarkably decreased. The results are shown in the following table. In the table, ++ indicates observation of remarkable enhancement, and + indicates moderated enhancement.
Compound Number Activity 1 + 3 + 5 + 6 ++ 9 + 12 ++ 14 + 15 + 18 ++ 19 ++ 21 ++ 23 + 24 ++ 25 ++ 26 + 28 ++ 31 ++ 35 + 36 + 38 + 41 ++ 42 ++ 43 + 44 + 48 + 53 + 55 + 56 + 58* + 64 + * not part of the present invention - The medicaments of the present invention enhance the effect of a cancer therapy based on the mode of action of DNA injury and reduce a dose of an anticancer agent and/or radiation. Therefore, the medicaments can reduce side effects resulting from the cancer therapy.
